Therefore, you should never allow user input to dictate the column names referenced by your queries, including "order by" columns, etc.

If you must allow the user to select certain columns to query against, always validate the column names against a white-list of allowed columns. You may use the table method on the DB facade to begin a query. The table method returns a fluent query builder instance for the given table, allowing you to chain more constraints onto the query and then finally get the results using the get method:.

You may access each column's value by accessing the column as a property of the object:. If you just need to retrieve a single row from the database table, you may use the first method. This method will return a single stdClass object:.

If you don't even need an entire row, you may extract a single value from a record using the value method. This method will return the value of the column directly:. If you would like to retrieve a Collection containing the values of a single column, you may use the pluck method. In this example, we'll retrieve a Collection of role titles:.

If you need to work with thousands of database records, consider using the chunk method. This method retrieves a small chunk of the results at a time and feeds each chunk into a Closure for processing. This method is very useful for writing Artisan commands that process thousands of records. For example, let's work with the entire users table in chunks of records at a time:. You may stop further chunks from being processed by returning false from the Closure :. If you are updating database records while chunking results, your chunk results could change in unexpected ways.

So, when updating records while chunking, it is always best to use the chunkById method instead. This method will automatically paginate the results based on the record's primary key:. This could potentially result in records not being included in the chunked results.

The query builder also provides a variety of aggregate methods such as count , max , min , avg , and sum. You may call any of these methods after constructing your query:. Instead of using the count method to determine if any records exist that match your query's constraints, you may use the exists and doesntExist methods:.

You may not always want to select all columns from a database table. Using the select method, you can specify a custom select clause for the query:. If you already have a query builder instance and you wish to add a column to its existing select clause, you may use the addSelect method:.

Sometimes you may need to use a raw expression in a query. To create a raw expression, you may use the DB::raw method:. Instead of using DB::raw , you may also use the following methods to insert a raw expression into various parts of your query. The selectRaw method can be used in place of select DB::raw This method accepts an optional array of bindings as its second argument:.

The whereRaw and orWhereRaw methods can be used to inject a raw where clause into your query. These methods accept an optional array of bindings as their second argument:.

The havingRaw and orHavingRaw methods may be used to set a raw string as the value of the having clause. The orderByRaw method may be used to set a raw string as the value of the order by clause:. The query builder may also be used to write join statements. To perform a basic "inner join", you may use the join method on a query builder instance. The first argument passed to the join method is the name of the table you need to join to, while the remaining arguments specify the column constraints for the join.

You can even join to multiple tables in a single query:. If you would like to perform a "left join" or "right join" instead of an "inner join", use the leftJoin or rightJoin methods. These methods have the same signature as the join method:. To perform a "cross join" use the crossJoin method with the name of the table you wish to cross join to. Cross joins generate a cartesian product between the first table and the joined table:. You may also specify more advanced join clauses.

To get started, pass a Closure as the second argument into the join method. The Closure will receive a JoinClause object which allows you to specify constraints on the join clause:. If you would like to use a "where" style clause on your joins, you may use the where and orWhere methods on a join. Instead of comparing two columns, these methods will compare the column against a value:.

Each of these methods receive three arguments: the sub-query, its table alias, and a Closure that defines the related columns:. The query builder also provides a quick way to "union" two queries together. For example, you may create an initial query and use the union method to union it with a second query:.

You may use the where method on a query builder instance to add where clauses to the query. The most basic call to where requires three arguments. The first argument is the name of the column. The second argument is an operator, which can be any of the database's supported operators. Finally, the third argument is the value to evaluate against the column.

For example, here is a query that verifies the value of the "votes" column is equal to For convenience, if you want to verify that a column is equal to a given value, you may pass the value directly as the second argument to the where method:. You may chain where constraints together as well as add or clauses to the query.

The orWhere method accepts the same arguments as the where method:. The whereNotBetween method verifies that a column's value lies outside of two values:. The whereIn method verifies that a given column's value is contained within the given array:.

The whereNotIn method verifies that the given column's value is not contained in the given array:. The whereMonth method may be used to compare a column's value against a specific month of a year:.

The whereDay method may be used to compare a column's value against a specific day of a month:. The whereYear method may be used to compare a column's value against a specific year:. The whereTime method may be used to compare a column's value against a specific time:.
